FontLoader

使用JSON格式中加载字体的一个类。返回Font, 返回值是表示字体的Shape类型的数组。 其内部使用FileLoader来加载文件。

你可以使用facetype.js在线转换字体。

例子

geometry / text / shapes
geometry / text

var loader = new THREE.FontLoader(); 
var font = loader.load( 
  // 资源URL 
  'fonts/helvetiker_bold.typeface.json', 
  // onLoad回调 
  function ( font ) { 
    // do something with the font 
    scene.add( font ); 
  }, 
  // onProgress回调 
  function ( xhr ) { 
    console.log( (xhr.loaded / xhr.total * 100) + '% loaded' ); 
  }, 
  // onError回调 
  function ( err ) { 
    console.log( 'An error happened' ); 
  } 
);

构造函数

FontLoader( manager : LoadingManager )

manager — 加载器所使用的loadingManager。默认值为THREE.DefaultLoadingManager.

创建一个新的FontLoader.

属性

# .manager : LoadingManager

加载器正在使用的loadingManager。默认值为DefaultLoadingManager.

# .path : String

所要加载字体的基本路径。 具体参考.setPath。 默认为undefined.

方法

# .load ( url : String, onLoad : Function, onProgress : Function, onError : Function ) : null

url — 文件的URL或者路径,也可以为 Data URI.
onLoad — 加载完成时将调用。回调参数是将要被加载的texture.
onProgress — 将在加载过程中进行调用。参数为XMLHttpRequest实例,实例包含total和loaded字节。
onError — 在加载错误时被调用。

从URL中进行加载,并将被加载的texture传递给onLoad。

# .parse ( json : Object ) : Font

json — The JSON structure to parse.

JSON格式进行解析,并返回一个Font.

# .setPath ( path : String ) : FontLoader

设置加载字体的基本路径或URL。当加载同一目录中下的许多字体时,此方法将很有用。
